X2-7x+12byx-3 divide of algebraic expression

​

x - 4

Step-by-step explanation:

Please write X2-7x+12 by x-3  as  x^2 - 7x + 12.  The " ^ " represents exponentiation.

Notice that  x^2 - 7x + 12  factors as follows:  (x - 3)(x - 4), and so the original division problem

x^2 - 7x + 12                        (x - 3)(x - 4)

becomes   = x - 4

      x - 3                                      x - 3

for all x except x = 3 (because we cannot divide by zero).
